current-state = vcc-data-transfer
vcc-type = terminating
[in ATMPVC-STAT/dsltnt-1]
circuit-name* = dsltnt-1
pvc-type = terminating
current-state = pvc-data-transfer
vcc-members = [ { shelf-1 slot-17 1 0 35 }]
For terminating connections, the value of the vcc-type and pvc-type parameters is
always terminating, and vcc-members always specifies a single member. The rest of
the parameters in the profiles are the same for terminating PVCs as for ATM circuits.
For details, see the Stinger ATM Configuration Guide.
Configuring system clocking (optional)
The Stinger MRT requires a clock source for its timing subsystem. By default, it uses a
built-in 8kHz clock as its timing source. You can configure the system to take its clock
source from a trunk port or from an external building integrated timing supply
(BITS) clock connected to the Stinger BITS connector.
Following is the relevant TAOS parameter, shown with its default value:
[in SYSTEM]
system-8k-clock = controller
Parameter
System-8K-Clock
Using the BITS clock source
The following commands cause the system to first attempt to use a BITS clock as its
clock source, and to use the built-in clock only if it does not find a valid BITS signal:
admin> read system
SYSTEM read
admin> set system-8k-clock = bits
admin> write
SYSTEM written
Loss of BITS signal indications and fall-back
If the system-8K-clock parameter in the system profile is set to bits and the system
detects a loss of signal, it displays the following message:
Stinger® MRT Getting Started Guide
Configuring Administrative Access, System Timing, and Startup Settings
Setting
Source for the master system clock.
With the default controller setting, the Stinger MRT
unit uses the built-in 8kHz clock.
If set to lim-or-trunk-module, the unit obtains its clock
signal from a trunk port that has been configured as an
eligible clock source, using the ports in order of their
priority. If no eligible trunk ports are available, it uses
the internal clock.
If set to bits, the unit sources its clock from the BITS T1
framer on its BITS connector.
